fix: enable imageCubeArray feature + transition all 24 shadow layers

Browse Source 
Two validation errors fixed:
1. imageCubeArray feature not enabled → added VkPhysicalDeviceImageCubeArrayFeatures
   to device creation chain (pNext: cubeArray → sync2 → dynamicRendering)
2. Shadow layers 18-23 in UNDEFINED layout → transition ALL 24 layers
   (MaxShadowLights * 6) instead of only numShadowLights * 6
   Descriptor references all 24 layers via CubeArray view
